GASOLINE NASH FURNACE.

Application filed September 20, 1921. 7 Serial No. 502,024.

Yowell, in the county of Delta and State of Texas, have invented new anduseful Iniproveinents in Gasoline Wash Furnaces, of which the followingis a specification.

My present invention is primarily directed to an improved hydrocarbonburner.

My primary object is to produce a burner oi? this character which isespecially designed for use in heating water for clothes washingpurposes.

In carrying out my invention, it is my aim to arrange in the bottom of acasing for a wash boiler a hydr0carbon burner of a particular andpeculiar construction through the medium of which the flame. will. bedirected against the bottom and against the sides adjacent to the bottomof the boiler, and thereby eifectively heat the boiler to boil the watertherein in anfexpeditious manner and with a small consumption of fuel,the flame 01"" the burner being readily regulated from the exterior ofthe boiler casing. i i i It is a still further object to produce ahydro-carbon burner-for clothes boilers in which gasolinewill bevaporized in a quick and efficient manner and when ignited, the flamethereof: will be directed against the boiler in a manner to'quickly boilthe water therein, the burner being arranged in the casing whichsupports the boiler and thereforeetiectively housed to prevent burning aor other injury being inflicted to the attendant or to persons in closeproximity thereto, while the construction is such as to positively vobviate 1' the liability of the ex* plosion ofthe gasoline.

It is a still further object to produce a gasoline wash furnace in whichthe boiler :tor the clothes is supported in asuitable casing, the latterhaving its base portion apertured for the admission of air, and anapertured bottomr above the first mentioned apertures, the lattersupporting thereon a hydro-carbon burner which includes a generatingchamber that has upwardly curved burner tubes extending from the sidesthereof t0;receivetherebetween the bottomof the boiler, while on theexterior of the casing, adjacent tothe top thereof there is supportedthe gasoline tank that has a delivery pipe leading to vaporizing tubesdisposed over the i OP 9f the burner, the outlet treaties member of thesaid tube communicating I with a compartment on one side ofthevgencrating chamber, the top of the chamber having a continuousirregularly shaped depression disposed. between the members comprisingthe vaporizing tube, the said de pressions forming a duct for thereception of gasoline which is let therein through a valve controlledport in the compartment, the gasoline in the said duct being ignitedtovaporize the fuel in the vaporizing tubes, permitting the vapor to enterthe compartment, and thereafter to be directed through i a. valvecontrolled pipe through an'opening in'the bottom of the compartment, thetop of the compartment between the ducts being provided with aperturesfor the va porized fuel. a I

The foregoing, and other objects which will appear as the nature of theinvention is better understood, maybe accomplished by a construction,combination and operative association of parts, such as is disclosed bythe drawings which accompany and which form part of thisspecification.in the drawings u 1 Figure .1. is a side elevation of the improvement,parts. being broken away and parts being in section. v

Figure 2 is a top plan view of the burner. Figure 3 is a-sectionl viewon the line 33 of Figure 2.

Figure 4 is a sectional view, on an en larged scale, and approximatelyon the line 4-4; or" igure 2. i

Referring now to the drawings in detail, the numeral 1 designates theclothes boiler,

The boiler .1 is constructed of some suitable metal and has its lowerand closed end rounded. The top of the boiler has a continuous head 2,theund-er face of which providing a shoulder for the substantiallyiirusto-conical hollow casting 3. The casing 3 is provided, adjacent toitslower end with a series of apertures 4, the same forming air inlets,while above the apertures there is secured in the casing the bbttornplate .The plate 5 is also provided with spaced apertures 6 that admitair to the; interior of the casingv and to the bottom of the boiler.

The casing has one oi its sides provided with anopeningthatis normallyclosed by a door ,7, the said door being arranged only a slight distanceabove the elevated base or bottom 5., N p

On one side of the casing, adjacentto the suitably braced, as at 9, andsupporting thereon a gasoline tank or reservoir 10.

The improved h 'dro-carbon burner is ar-{ ranged in and at the center ofthe casing 3, the same being supported on legs 11 which elevate the sameabove the base or floor 5 The hydro-carbon burner has its body por tionin the natureof a generating chamber 12. The chamber is in the nature ofa'easting, being preferably round in plan, and the same has upon its hattop a continuous depression, which defines central longitudinal passages13 connected at their ends by rounded passages let, the end longitudinalpassages being connected by a curved passage 15 disposed adjacent to therounded periphery. of the chamber 12, while the in nermost longitudinalpassage, indicated for formed'on one side'ofvthe chamber 12. This branch16 is in-a line with a ported boss 18 that projects inward of thecompartment 17, the said boss having itsport flared inwardly from'itsin'n'er end toprovide a seat for a needle valve 19, The stem of thevalve 19Lis threaded and'is received in a threaded boss 20that projectsfrom one of the) sides of the'compartment 17.

The stem of the" valve 19 passes through a suitable opening inthe casing3,t'he said stem having its outer 'end provided with the usual operatinghandle whereby the valve can be operated exteriorly'o'f the casing 3.

The outlet pipe for the gasoline tank or reservoir is indicated by thenumeral 21, and has an angle branch which passes through the casing 3,below the apertured elevated baseor floor 5 thereof, the said passageindicated by the numeifal 22 communicating with a vertically disposedextension 23 which has an angle branch arranged over the top of thegenerating'chamher, 12 and which may be integrally formed with or haveconnectedthereto the vaporiz'ing' tube 24. The vaporizing tube 24 isshaped to substantially correspond with the depressions that provide thegasoline ducts on the u er; face of the generating chamber, that is thevaporizing t ubecomprises longitudinal branches connected by roundedbranches, the outermost longitudi nal branc'hesbeing connected by arounded branch of a greater circumference than the inner rounded branch,and the inner end ofthe tube, indicated for distinction by thenumeralj25 communicates with the/compartment 1'8. The compartment 18,has a bottomi portion which projects below the generating chamber 12,and secured thereto there is a pipe 26 that has its outer. end

closed, but its top portion provided with one or more apertures 27arranged directly over a central opening 28 in the bottom of thegenerating chamber 12. The top of the generating chamber is providedwith spaced apertures 29 between the gasoline ducts thereon.

By reference to Figure 1 of the drawings,

it will be noted that the vapor outlet 27 is disposed a considerabledistance away from the bottom of the generating chamber, so that airwill freely mix with the vaporized gas before entering the chamber 12,and

by also referring to the said Figure l, it will be seen that the' vaporconducting pipe 26 is controlled by a needle valve the said valve havinga'threaded stein which isle ceived in the threaded bore of a boss 31 onone of the sides of tliecompartinent 17. The stem of the valve 30 passesthrough an opening in'the casing 3, the outer endof the, said stem beingprovided with an'operating head or handle.

The sides of the generating chamber are provided with any desired numberof spaced threaded openings, and in each'of these openings thereisscrewed a burner tube 32; Each burner tube is directed upwardly in thecasing 8, the burner tubes beingdisposed to receive therebetween thelower rounded end of the boiler 1. The tubes 32 have their outer endsclosed by plugs 33'an'd their inner faces areaperturechas at 34'. i

The operation of thedevice may be brief} ly described as follows: I

The gasoline'fiows" from the tank or reser voir' 10 so that apa'rt'thereof is at all times received in the compartment 17. By openingthe needle valve 19, a quantity'ofthe gasoline willbe permitted to entertheduc ts provided by the depressions in thetop of the generatingchamber. The valve isthen closed" and the, gasoline which is received inthe depressions, that really providethe gasoline trough, isignitedrtheiflame thereof being" directed against the coiled vaporizingtubes, generating the fuel which passes through the said; tubes; Thisfuel enters the compartment 17, and the valve 30 is unseat ed permittingthe said fuel; to pass through the conductor pipe 26, port 27 andopening 28 into the generating chamber 12. The" fuel will pass throughthe openings 29 and through the burner tubes 32. The ignited gasoline inthe ducts, will light the fuel that passes through the openings 29 andthrough the apertures in the burner tube sfand it will be thus'notedthat the flames 111 be positively directed against the bottom and alsoagainst thesides adjacent to the bottom ofthe boilerl. The flame can beregulated by adjusting the valve and-it is thought that the foregoingdescription, when taken in connection with the'dra'wings willfu'llysetffor'th the construction, operation and a dvantages'oftheimprovement to thoseskilled in the art to which such inventionsrelate: It is to be understood, however, that the nature of theinvention is such as to render the same susceptible to changes, andtherefore I am not to be restricted to the precise structure illustratedand described, but am entitled to make all such changes therefrom asfall Within the scope of What I claim.

Having described the invention, I claim:

1. In a hydro-carbon burner, a hollow casting having an apertured topand said top on its outer face provided with communicating irregularlyshaped grooves which provide a trough for gasoline, means controllingthe gasoline fed into the trough, a vaporizing tube above the chamber,means introducing a gaseous fluid therethrough and the said tubesdesigned to be heated by the ignition of the gasoline in the trough,said chamber having a compartment receiving the vapor from the tubes, anoutlet pipe for the chamber for delivering the gas through the bot-tomof the chamber, a valve controlling the passage through said pipe, andoutwardly directed upwardly curved apertured burner tubes on the sidesof the chamber.

2. In combination with a boiler, a casing supporting the same having airinlet openings adjacent to the bottom thereof and an apertnred baseabove said openings, of a hydro-carbon burner including a hollow castingsupported above the base, said casting having an apertured top andhaving circuitons depressions on the outer faces thereof, said casinghaving a compartment on one side thereof communicating with saiddepression, a valve controlling said communi cation, a vaporizing tubeof a contour of that of the depression arranged above the chamber andcommunicating with the compartment, means delivering gasoline into thevaporizing tube, a fuel outlet pipe for the compartment communicatingwith the bottom of the chamber, but spaced therefrom, a valvecontrolling said communication, and upwardly directed apertured burnertubes secured to the sides of the casing and disposed to'surround thebase and sides of the boiler at the base portion thereof.

In testimony whereof I affix my signature.
